NECK-BEARING.

Specification of Letters Patent.

Patented July 22, 1919.

Application filed May 14, 1919. Serial No. 297,111.

To all whom it may concern:

Be it known that I, SVEN AUGUST EsKIL- SON, a subject of the King ofSweden, and resident of Torstensonsgatan 4, Stockholm, in the Kingdom ofSweden, have invented certain new and useful Improvements inNeck-Bearings, of which the following is a specification, referencebeing had therein to the accompanying drawing.

This invention relates to a yielding neck bearing, adapted especially tothe spindle of the drum in cream separators. As a yielding memberbetween the sleeve of the spindle and for instance the frame of theseparator the well known arrangement of a wire or strip of metal or anyother springy material and bent into a zigzag shape is used, which isshaped into a ring and at the ends of each part bears against the saidsleeve and at an intermediate portion of the parts bears against theframe or vice versa. According to the invention the parts of the saidring extend in an oblique direction peripherically from the bends,connecting the parts, toward an intermediate portion of the parts, thesaid portion being preferably straight. Owing to this arrangement of theparts the yielding capacity of the ring is improved and besides theintermediate portion of the parts bears against the sleeve or the framerespectively in a more suitable manner than hitherto.

In the accompanying drawing Figure 1 is a side view partially a sectionof a neck bearing arranged in accordance with the invention. Fig. 2 is asection on the line 2 to 2 of Fig. 1.

l is the sleeve of the spindle and 2 may designate the frame of theseparator. 3 is the yielding ring, formed of a wire bentinto a zigzagshape and then into a ring; As shown in Fig. 1 the wire is bent in sucmanner, that its parts extend in an oblique direction periphericallywith relation to the rin from their ends toward their intermediateportion. The intermediate portion of each part is preferably straightfor a suitable length, as shown. In the, drawlng the ends of the partsbear against the sleeve 1, while their intermediate portion bearsagainst the frame 2. The wire may, however, be so bent, that the ends ofthe parts bear against the frame and their intermediate portions bearagainst the sleeve.

Owi to the described arrangement of the parts of the ring the parts donot yield radially or straight toward and from the center line of thebearing, as is the case in rings hitherto used,but each part swingsabout a line, which connects the ends of the parts, or swings on theends of the parts as supporting polnts. Consequently, the yieldingevidently is considerably softer than in rings hitherto used and made ofthe same material and having the same dimensions. Owing to the fact thatthe parts are straight .at their intermediate portions and consequentlybear against the frame by means of a considerable portion of theirlength, the wear of the parts is reduced and the parts do not tend tocut into the frame, as, on the other hand, is the case, when the partsre spectively bear against the frame substantially at one point.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a neck bearing the combination of a sleeve, an outer bearinsurface, and a yielding ring-shaped mem er inclosing the said sleeve andconsistin of a wire or strip of metal or the like bent mto a zigzagshape, the parts extending in an oblique direction peripherically fromthe bends connecting the parts, to the intermediate portions of theparts, and hearing at the ends against the said sleeve and at theintermediate portion against the said bearing surface or vice versa.

2. In a neck bearing the combination of a sleeve, an outer bearinsurface, and a yielding ring-shaped mem er inclosing the said sleeve andconsistin of a wire or strip of metal or the like bent mm a, zigzagshape, the parts of the ring extending in an oblique directionperipherically from the bends, connecting the arts, to an intermediatestraight portion of the parts, and bearing at the ends against the sa1dsleeve and at the intermediate portion against the said bearing surfaceor vice versa.

In witness whereof I have hereunto signed my name.

' svnN AUGUST ESKILSON.
